2008 Performance Assessment of Mastoidectomy

1.
Temporal Bone Dissection Criteria

We are using the temporal bone surgical simulator as a potential device to objectively assess performance on a basic mastiodectomy. As we work towards creating automated metrics to quantitatively evaluate surgical performance, we would like to first determine which metrics are considered the most important and relevant in the assessment of a temporal bone dissection. You will need approximately 15 minutes to complete this survey. Please address any concerns or questions under 'Comments' listed under each section.

The following list of metrics is compiled from temporal bone dissection criteria published by the University of Toronto, Stanford, and the Ohio State University (references cited below).
